Protein detail:
| Protein name | ORF3a protein |
| Uniprot protein ID | P0DTC3 |
| Protein length | 275 amino acids |
| Protein description | ORF3a is a non-structural protein of SARS-CoV-2 localized at the surface. It is the largest accessory factor that contains 275 amino acids, and shows broad functions, such as enhancing viral entry within the host, regulating the pro-inflammatory cytokine and chemokine production, participating in ion channel formation as well as modulating release of virus from the host cell. |

| Title | Dynamics of severe acute respiratory syndrome coronavirus 2 genome variants in the feces during convalescence |
| Author | Yi Xu,Lu Kang,Zijie Shen,Xufang Li,Weili Wu, |
| Evidence | We identified 229 intra-host variants at 182 sites in 18 fecal samples. Among them, nineteen variants presented frequency changes > 0.3 within 1-5 days, reflecting highly dynamic intra-host viral populations.(Figure3) |
